Answer:

the interior angles of any triangle are equal to 180.

In other words m<BAC + m<ABC + m<ACB = 180.

Therefore,

(3x-1) + (8x-35) + (6x-5) = 180

Now that we have an equation, we can solve for x:

(3x-1) + (8x-35) + (6x-5) = 180

Combine like terms:

3x+8x+6x-1-35-5

17x-41 = 180

Add 41 to each side:

17x-41+41 = 180+41

17x=221

Divide by 17 on both sides:

x=13

Now to check if this is correct we need to plug in x for each equation and the three numbers combined should equal 180.

3x-1

3(13)-1

6x-5

6(13)-5

78-5

8x-35

8(13)-35

104-35

Now we just add them to see if they equal 180

38+73+69 = 180

x=13 is valid

4. Here is a linear equation: y=1/4 x + 5/4

4vir4ik [10]

Step-by-step explanation:

"Solutions to the equation" just means that they are points on the line. To find out if these two points land on this line, plug each one in, like this:

1.5 = (1/4)(1) + (5/4)

1.5 = (1/4) + (5/4)

1.5 = (6/4)

1.5 = 1.5

Since the expression is true, this point is on the line.

Do the same process for the second point (remember a point is formatted (x,y)) and see if it is also a point on the line.

To find the x-intercept, simply plug in 0 for y and see what you get. It should look like (x,0).

PLEASE HELP!!! Given the functions, f(x) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the

Brums [2.3K]

Answer:

The domain restriction for (f/g)(x) is x=7

Step-by-step explanation:

we have

$f(x)=6x+2$

$g(x)=x-7$

$(f/g)(x)=\frac{6x+2}{x-7}$

Remember that

the denominator can not be equal to zero

Find the domain restriction

x-7=0

x=7

therefore

The domain is all real numbers except the number 7

(-∞,7)∪(7,∞)
